I LEANDER K. BINGHAM, OF NEW YORK, N. Y.

APPARATUS FOR MAKING PRlNTERSiROLLERS SPECIFICATION forming part ofLetters Patent No. 413,894, dated October 29, 1889.

Application filed March 13, 1889.

To all whom it may concern:

Be it known that I, LEANDER K. BINGHAM, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Apparatus forMaking Printers Rollers; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and usethe'same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.-

Figure 1 is a transverse section of a portion of a cylinder having theinvention, the section being on line as as, Fig. 2. Fig. 2 isahorizontal section looking down within the cylinder.

This invention relates to improvements in apparatus for making printersrollers, more particularly to the construction of the lower end of suchapparatus.

The invention is illustrated as being used with an apparatus composed ofa cylinder containing a number of mold tubes.

The invention consists in the construction hereinafter pointed out. 7

.In the drawings hereto annexed, the letter A indicates the usualcylinder to be provided with the trunnions and steam and water inlet andoverflow, as is well understood in this class of devices. The bottomheadB drops at I), having the circumferential rim b, by which it is tobe attached to the rim a of the cylinder-body. This head B has the holes0 0 arranged in circles. tween the outer ones 0, as shown in Fig. 2. Onthe under sideof the head B at each hole is made a countersink c andfrom each countersink a bottomless channel 0 runs to the periphery ofthe head. Into the countersink'and up through the holes c c are insertedthe glands D, having the threads 01 and provided with the packing d.Engaging the The inner ones a come be- Serial No. 303,104- [No model.)

threads d are the lower ends 8 of the mold tubes E, the upper ends ofwhich are held suitably in the top head of the cylinder.

Supported under the head B is the movable bottom F. This bottom is madewith a rim f and receives within it the head B. There is a nozzle fleading within the bottom F. This bottom is held in place by a rod fwhich passes down through the cylinder, and the bottom F is held thereonby a nut f.

In use the roller-stocks are inserted into the mold-tubes in the usualway, and the bottom F is put in place and turned until the nozzle fregisters with one of the channels 0 when roller-composition is admittedthrough the nozzle under pressure from a head or otherwise. V Thecomposition rises up and fills a mold-tube. When this is filled, thebottom is turned until the nozzle registers with another channel, and soon until the mold-tubes are filled. Steam and water are admitted, as.

usual, and after the ro lers are formed they are taken out in the usualway, the bottoinF being removed.

Having thus described my invention, what I claim is l. The combinationof the cylinder, its mold-tubes, the bottom head having the holes forthe tubes, the countersinks around the holes, and the bottomlesschannels running from the counter-sinks to the edge of the head with thebottom provided with the nozzle, as set forth.

2. The combination of the cylinder, its mold-tubes, the bottom headhaving the holes for the tubes, and the bottomless channels running fromthe holes to the edge of the head with the bottom provided with thenozzle, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
